Go to FTAHQ.com and read up on it.All the info is there.As far as purchasing them,there are distributors all over the city of Toronto.I personally deal with a place on Matheson just west of Dixie in Mississauga.It's tight beside the stage West hotel.Viewsats will run you anywhere from $120 to $160 depending on which unit you purchase.The Viewsat Ultra has a usb port which is very helpful with loading bin files.
